Dr. Ivano Pusterla and Prof. Jeffery Bode of ETH-Zürich and Nagoya University's Institute of Transformative Bio-Molecules (ITbM) have succeeded in the first synthesis of oxazetidine amino acids as a new ligation partner for the rapid and chemoselective synthesis of proteins.http://phys.org/news/2015-06-rapid-chemical-synthesis-proteins-amino.html

A study carried out at Zelinsky Institute of Organic Chemistry of the Russian Academy of Sciences (Moscow) has shown that partial replacement of chemical compounds by their natural analogs may surprisingly lead to even more toxic products. The article published in Toxicology Research describes increased toxicity of ionic liquids after incorporation of amino acid residues.http://phys.org/news/2015-03-misuse-sustainability-concept-toxic-chemical.html

The action of this molecule is important for a number of cell functions including axonal transport and chromosome segregation, and its dysfunction is known to lead to a congenital developmental brain disorder known as lissencephaly.http://phys.org/news/2015-01-revealing-molecular-motor.html
Cell & Microbiology Mon, 12 Jan 2015 09:42:02 EDTnews340278112Fight or flight and the evolution of painHard wired into the survival mechanisms of all animals is the perception of pain. Different stimuli, such as heat or cold, foul odors, chemicals or a blunt blow can trigger pain receptors in the body that, in the blink of an eye, jolt the body into classic fight or flight responses.http://phys.org/news/2014-01-flight-evolution-pain.html
Biotechnology Tue, 07 Jan 2014 20:00:01 EDTnews308332472Protein study suggests drug side effects are inevitableA new study of both computer-created and natural proteins suggests that the number of unique pockets – sites where small molecule pharmaceutical compounds can bind to proteins – is surprisingly small, meaning drug side effects may be impossible to avoid. The study also found that the fundamental biochemical processes needed for life could have been enabled by the simple physics of protein folding.http://phys.org/news/2013-05-protein-drug-side-effects-inevitable.html
Biochemistry Mon, 20 May 2013 15:00:20 EDTnews288270799Water splitting: Ultrahigh resolution data reveals reaction mechanismsOxygenic photosynthetic organisms utilize energy from the sun to split water into protons, electrons and oxygen—products vital to life on earth. The process takes place through light-induced electron transfer reactions in a membrane protein complex photosystem II, but so far the resolution of structural studies on the protein complex has been too limited to ascertain the mechanism of these reactions in detail.http://phys.org/news/2012-09-ultrahigh-resolution-reveals-reaction-mechanisms.html

Spread through the air from one person to another, tuberculosis is responsible for approximately two million deaths per year, worldwide, and the emergence of drug resistant forms, specifically MDR- and XDR-TB, is an escalating challenge.http://phys.org/news/2012-04-treatment-tuberculosis-biochemist.html

Michigan State University scientists, however, see them in a different light.http://phys.org/news/2011-04-scorpion-venom-bad-bugs.html
